Intellectual Property

We defend and foster intellectual property every day, within Japan and throughout the world.


We deal daily in IP matters in Japan, and can quickly and expertly handle IP matters in more than 100 countries around the world. Our lawyers frequently draft and negotiate complex licenses and agreements involving patents, trademarks, copyrights (including software copyrights) and/or know-how – in Japan, the United States, the EU, and other major jurisdictions. We can register new trademarks and designs for clients in Japan and elsewhere. When disputes arise, we represent clients in intellectual property infringement matters (patent, trademark, copyright, etc.), including in disputes arising out of parallel imports or large agreements containing intellectual property. IP is fundamental to the corporate existence of many of our clients, including medical equipment manufacturers, car parts manufacturers, and clothing designers. Our services have won the highest trust from clients all over the world.
